SINK TRAP AND LIFT.

Application filed April 9,

T all whom it may concern:

Be it known that I, JOSEPH A. OLAUGH- LIN, a citizen of the UnitedStates, residing at Hutchinson, in the county of Reno and State ofKansas, have invented certain new and useful Improvements in a Sink Trapand Lift, of which the following is a specification.

This invention appertains to novel improvements in combination watertraps and lifts and the primary object of the present invention is toprovide novel means for lifting water from waste traps in basements andthe like to the sewer pipe, said means including a novel device forautomatically preventing the backing up of the water in the trap and theconsequent flooding of the basement should the sewer become stopped upor in any other way rendered unfit to carry away the sewage.

Another prime object of the invention is the provision of an automaticlift for water traps including a novel valve arrangement so constructedas to permit the flowing of the water up past the same to the sewer pipebut prevent the downward flow of water past the same into the trap.

A further prime object of the invention is the provision of a drain of anon-automatic or of an automatic construction within an airtight casingconnected to a laundry drain or cesspool for facilitating the lifting ofthe water for a considerable distance above the laundry drain orcesspool.

A further prime object of the invention is the provision of novel meansfor changing the drain either into an automatic device or into anon-automatic device, the drain when constructed to work a-utomaticallyembodying a valve controlled float, which is arranged to operate to shutoff the con-- nection between the drain and the trap when the water inthe trap falls below a predetermined level.

A still further object of the invention is to provide an improved deviceof the above character, which will be durable and eflicient in use, onethat will be simple and easy to manufacture, and one which can beincorporated in a plumbing system at a small cost.

With these and other objects in view, the invention consists in thenovel construction,

arrangement and formation of parts, as will be hereinafter morespecifically described, 5 claimed and illustrated in the accompanyingdrawings, in which drawings:

Figure 1 is a fragmentary side elevation of my improved drain and trapconnected with a plumbing system, the drain being shown of anon-automatic construction, the trap being shown in cross section.

Figure 2 is an enlarged vertical section through the improved drainportion of the invention, the drain being of a non-automatic character.

Figure 3 is a detail horizontal section through the drain taken on theline 3-3 of Figure 2, and

Figure 4c is an enlarged vertical central 7 longitudinal section throughthe improved drain constructed to operate automatically.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the 7 several views,the letter A generally indicates the improved trap and drain and B aplumbing system with which it is incorporated.

As clearly shown in Figure 1 of the drawings, the plumbing system Bincludes a laundry drain or sink 5 located in a basement or the likebelow the main sewer pipe 6. As shown water is supplied to the laundrytub or sink 5 by means of supply pipes s5 7 one of which, preferably thecold water pipe has connected thereto a branch pipe '8 which leads to apart of the improved drain and trap A, as will be hereinafter more fullydescribed. The outlet of the o0 laundry tray or sink 5 is connected tothe trap and drain A by means of a pipe 9 which will be also hereinaftermore fully described. 1

The improved trap and drain A shown 05 in Figures 1 to 30f the drawingsis of the non-automatic nature and consequently a hand operated globevalve or the like 10 can be incorporated in the length of the pipe 8 forcontrolling the flow of water there- 10 through to the drain.

The drain and trap A comprises an outer casing 11 which can be of theairtight nature and to which has connected at the lower end thereof thedrain pipe 9 from 5 the sink or laundry tray 5.

Disposed axially within the airtight casing 11 is the drain portion 12per se of my invention. This drain portion 12 embodies a tubular outershell 13 to which is threadedly or otherwise connected an outlet cap 14at its upper end. This outlet cap 14 in turn supports an inner tubularsleeve 15 which comprises the portion through which the water or othersewage is adapted to flow. The upper end of the sleeve 15 has connectedthereto the outlet sewer pipe 16 which extends to the main sewer pipe 6.It is to be understood at this point that my invention is particularlyadapted for use in basements, cellars and the like where the main sewerpipe is located above acesspool, laundry tub or the like so as to insurethe :efiiective carrying oil of the water ZfI'QIIl the basement to themain sewer and thus prevent theflooding of the basement.

Arranged within the sleeve 15 at a point intermediate its ends I providea valve seat 17 having an axial way 18 therethrolgh. A ball valve 19 isadapted to normally fit upon the seat 17 and the provision 01 thisseateand valve forms one of the most important features of my invention.The lower end of the tubular pipe or housing 13 is closed by a removablecap 20, when the device is of a non-auto=matic nature as shown inFigures 1 to 3 inclusive The lower end otthe sleeve 15 can haveconnected therewith in any preferred way a nozzle 21 which is arrangedbelow the valve seat 17. plurality of ports 22 are formed in the tubularpipe or housing 13 and communicate with the inner sleeve 15 below thevalve seat 17. These ports permit the flow of the sewage from the-casing11 into the inner sleeve :15.

The water branch feed pipe 8 is connected with the'cap 14L andthe upperend of the tubular pipe orrhousing 13 as is clearly shown in Figure 2 ofthe drawings.

In operation of the improved drain and trap, when it is desired :tocarry the water off from the casing 11, which has collected therein fromthe sink tub orwthe like 5, the valve 10 is open which permits the flowof water between the tubular pipe or housing 13 to the inner sleeve 15.This water will flow downto the lower end of the drain and then upthrough the nozzle 21 through the sleeve 15, up the pipe 16 and into thesewerage 6. This flow of water :will unseat the valve 19 and cause asuction inthe ports which will suck in the water from the easing'llandthus effectively raise the sain to the-main sewerage pipe 6. Iii-torany reason the sewerage pipe -6 ispreventedtrom carrying oft the waterand othersewage and-it thewater and sewage-fromthe main pipe 6 startstovback up in the drain, the valve :19 will :be forced on its seat 17which will .e-tl ec- :tively. preve nt the collecting of the sewage intothe casing 11 dirom :t-he'niai-n sewerage sinking the same level withthe floor of the cellar or basement and provide recesses in the upperwall of the casing.

In Figure 4 of the drawings I have shown the automatic arrangement forthe drain and this drain is constructed identically with the drain shownin Figures 1 110.3 inclusive with the exception that :the lower cap isremoved to the automatic device incorporated with the tubular housing 13in lieu of-said cap.

As shown the automatic drain comprises an outer'tubular housing 25 towhich is connected at its outer end a cap 26 for supportingthe innersleeve 27 which leads ;to the sewerage pipe 6. The can 26 also receivesthe branch-water pipe 8 as in the drain previously described. At pointabove its lower end, the sleeve 27 is provided witha valve seat 28 onwhich is adapted-to seat -the ball valve 29. The lextreme'lower endofthe sleeve 27 is provided with a combined nozzle and valve seat 30onwhich is adapted to tit the sliding valve head 31, which is connectedto an operating plunger 32. The plunger 32 is slidably mounted in asuitable packing gland 33 carried by the cap 341 which is threaded withthe lower end of the :tubular housing 28. Suitable ports 35 are providedfor permitting the :flow of the sewage from the casing 11 into thesleeve 27 betweenthe valve seats 28 and 30. As shown these ports 35include short lengths of tubes which extend through-the tubular housing25 and the sleeve 27.

A float 36 of annular .-cons,truction is slidably mounted on-the tubularhousing 25 and is adapted to be raised and lowered by the water in thecasing 11. The lower end of thefloat 36 has-rigidly connected-thereto atdiametrically opposite points depending arms 37 which arein turnconnected by a pin and slot connection 38 with lovers 39 which arepivoted as at 10 to depending supporting; brackets 41 carried by-the cap34;. The iiiner ends otthe levers 39 are'piv otal-ly connected as at 412to the plunger of the valve head 31 Now it is ohviousthat when thecasing 11.

becomes filled with water that thefloat 36 will be raised which willmove the valve bodv '31'below and oli' of the seat 30 which will permitthe flow otthe water from the branch pipe 810 enter into the sleeve 27and force the valve 29 from its seat, which will suck the water from-thecasing 111 and as soon as the water or other sewage inethe easing llfalls below a predetermined level, the float 36 will fall and thus seatthe valve body 31 and prevent the water flowing further through thevalve seat 30 into the sleeve 27.

From the foregoing description, it can be seen that I have provided anexceptionally simple and durable means for insuring the efl'ectivelifting of water from traps and the like to overhead sewerage pipeswhich will effectively prevent the backing up of the water into the trapfrom the sewerage pipes should the same become clogged up through anycause.

Changes in details may be made without departing from the spirit or thescope of this invention.

lVh-at I claim as new is:

1. In a combined trap and water drain tor plumbing systems, a casinghaving an inlet therein for receiving sewage, an axially disposedtubular housing extending into the casing, an axially disposed sleevearranged within the housing and extending exterior-l thereof forconnection with the sewer pipe, a water supply pipe communicating withthe upper end of the housing and arranged for permitting the flow ofwater around the lower end of the sleeve and up into the sleeve, andinlet ports communicating with the sleeve for permitting the sucking ofwater into the sleeve from the casing.
